fat: restructure export_operations

2013-04-30T01:28:40Z

Define two nfs export_operation structures,one for 'stale_rw' mounts and the other for 'nostale_ro'. The latter uses i_pos as a basis for encoding and decoding file handles. Also, assign i_pos to kstat->ino. The logic for rebuilding the inode is added in the subsequent patches.

Merge branch 'for-3.8' of git://linux-nfs.org/~bfields/linux

2012-12-20T22:04:11Z

Pull nfsd update from Bruce Fields: "Included this time: - more nfsd containerization work from Stanislav Kinsbursky: we're not quite there yet, but should be by 3.9. - NFSv4.1 progress: implementation of basic backchannel security negotiation and the mandatory BACKCHANNEL_CTL operation. See http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues for remaining TODO's - Fixes for some bugs that could be triggered by unusual compounds. Our xdr code wasn't designed with v4 compounds in mind, and it shows. A more thorough rewrite is still a todo. - If you've ever seen "RPC: multiple fragments per record not supported" logged while using some sort of odd userland NFS client, that should now be fixed. - Further work from Jeff Layton on our mechanism for storing information about NFSv4 clients across reboots. - Further work from Bryan Schumaker on his fault-injection mechanism (which allows us to discard selective NFSv4 state, to excercise rarely-taken recovery code paths in the client.) - The usual mix of miscellaneous bugs and cleanup. Thanks to everyone who tested or contributed this cycle." * 'for-3.8' of git://linux-nfs.org/~bfields/linux: (111 commits) nfsd4: don't leave freed stateid hashed nfsd4: free_stateid can use the current stateid nfsd4: cleanup: replace rq_resused count by rq_next_page pointer nfsd: warn on odd reply state in nfsd_vfs_read nfsd4: fix oops on unusual readlike compound nfsd4: disable zero-copy on non-final read ops svcrpc: fix some printks NFSD: Correct the size calculation in fault_inject_write NFSD: Pass correct buffer size to rpc_ntop nfsd: pass proper net to nfsd_destroy() from NFSd kthreads nfsd: simplify service shutdown nfsd: replace boolean nfsd_up flag by users counter nfsd: simplify NFSv4 state init and shutdown nfsd: introduce helpers for generic resources init and shutdown nfsd: make NFSd service structure allocated per net nfsd: make NFSd service boot time per-net nfsd: per-net NFSd up flag introduced nfsd: move per-net startup code to separated function nfsd: pass net to __write_ports() and down nfsd: pass net to nfsd_set_nrthreads() ...

fs, exportfs: add exportfs_encode_inode_fh() helper

2012-12-18T01:15:27Z

We will need this helper in the next patch to provide a file handle for inotify marks in /proc/pid/fdinfo output. The patch is rather providing the way to use inodes directly when dentry is not available (like in case of inotify system).

exportfs: add FILEID_INVALID to indicate invalid fid_type

->encode_fh() API change

2012-05-30T03:28:33Z

pass inode + parent's inode or NULL instead of dentry + bool saying whether we want the parent or not. NOTE: that needs ceph fix folded in. Signed-off-by: Al Viro

vfs: Add name to file handle conversion support

The syscall also return mount id which can be used to lookup file system specific information such as uuid in /proc//mountinfo Signed-off-by: Aneesh Kumar K.V Signed-off-by: Al Viro

exportfs: Return the minimum required handle size

2011-03-14T13:15:28Z

The exportfs encode handle function should return the minimum required handle size. This helps user to find out the handle size by passing 0 handle size in the first step and then redoing to the call again with the returned handle size value.

nilfs2: make snapshots in checkpoint tree exportable

2010-10-23T00:24:34Z

The previous export operations cannot handle multiple versions of a filesystem if they belong to the same sb instance. This adds a new type of file handle and extends export operations so that they can get the inode specified by a checkpoint number as well as an inode number and a generation number.

commit_metadata export operation replacing nfsd_sync_dir

2010-02-20T21:13:44Z

- Add commit_metadata export_operation to allow the underlying filesystem to decide how to commit an inode most efficiently. - Usage of nfsd_sync_dir and write_inode_now has been replaced with the commit_metadata function that takes a svc_fh. - The commit_metadata function calls the commit_metadata export_op if it's there, or else falls back to sync_inode instead of fsync and write_inode_now because only metadata need be synced here. - nfsd4_sync_rec_dir now uses vfs_fsync so that commit_metadata can be static Signed-off-by: Ben Myers Reviewed-by: Christoph Hellwig Signed-off-by: J.
